South Park Roadway and Drainage Partnership Project

The South Park industrial area has been impacted by overland flooding from the Duwamish River and localized flooding from an undersized and inadequate public storm drain system. This Osborn-led project’s goal was to reduce flooding by installing more than 4,000 LF of new public storm drainage system and improve transportation with construction of approximately 1.5 lane miles of new right of way improvements, including sidewalks, trees, and roads designed for the industrial uses. Today, the neighborhood is safer with transportation improvements, healthier with the addition of trees and vegetation, and more productive with the reduction in frequency of flooding events.
